Most of what I want is available via snmp such as user name, ip address, the user mac address, and such. However, PPPoE Intermediate Agent tags - CircuitID and RemoteID - are apparently not available anywhere in snmp. That information apparently only shows up using the cli command "show pppoe session all", and so my tool polls with snmp first, and then follows up with a text login to the router and parses the cli output, finally stitching it all together at the end. Its quite hairy.

I've went thru cisco's snmp object navigator quite a bit and I came up empty. I've also spent lots of time doing some pretty deep walks of the snmp tree trying to just pick out the right info but again it just doesn't seem to be implemented. Im sort of resigned to the idea that, yeah, they just don't make that available via snmp. Id just like some confirmation from others that my situation here isn't actually unusual and parsing the output from the cli for certain info is an accepted practice?

It's neither particularly desirable nor unusual to have to do this.  :-(  I haven't looked at the BGP MIBs lately, but they were rife with omissions of this sort last time I looked.

Any chances you can get the data you need out of your RADIUS logs?
